This would confirm our assumption that it's libxml which treats \r
differently depending on the output format.
at the source the XHTML serialization code seems to call
xmlEscapeContent in xmlIO.c. There's also xmlEscapeEntities in xmlsave.c
but that uses hex char refs. Those two functions don't make an exception
for XHTML content.
Personally, I think libxml shouldn't escape "\r" at all.
As one function distinguishes between HTML and XHTML and the others escape
\r I wonder what the use cases looked like. So far it would also make more
sense to me if \r is not escaped for XHTML (at least one popular reading
system for ePub files - which contain XHTML files - shows a question mark
for entities).
